مسلسل جدوجہد کا میابی کی کنجی ہے

مسلسل جدوجہد کا میابی کی کنجی ہے
ایک بچہ ہاتھ میں کتابوں سے بھرا بیگ اٹھائے خراماں خراماں گاؤں کے مشرقی کونے پر موجود سکول کی جانب جارہا تھا۔ چہرے پر بشاشت کے آثار نمایاں تھے۔ کسی منزل پر پہنچنے کا شوق دامن گیرتھا، اپنے بوڑھے والدین اور بہن بھائیوں کی خدمت کا جذ بہ بھی پیش نظر تھا۔ یہی شوقِ تعلیم اس کو اپنے مقصد کی تکمیل کے لیے ممدو معاون ثابت ہوسکتا تھا۔ اس کے شب و روز حصول مقصد کی لگن میں گزررہے تھے۔ دریں اثناء اچانک جاں گسل صدمہ پیش آیا اور اس کے ارمانوں پر پانی پھیر گیا۔ آفت آسمانی سیلاب کی صورت میں اس کے گھر کو قبرستان بنا کر چلی گئی۔ اور گھر کا جملہ سامان عذاب کی صورت میں آنے والے سیلاب نے ختم کر دیا۔ اپنی اس گفتگو کے دوران اس کی آنکھوں میں آنسوؤں کی شکل میں نمی کے آثار نمایاں تھے۔ عظیم منصب پر فائز شخص نے موونگ چئیر پراپنے جسم کو دائیں بائیں متحرک کرتے ہوئے اپنی کامیابی کے راز کو فاش کیا اور کہا کہ شوق اگر چہ کا میابی کے لیے یوں ہے جیسے مچھلی کے لیے پانی ، زندہ رہنے کے لیے خوراک، اور سانس لینے کے لیے ہوا، لیکن شوق کے ساتھ محنت اور مشقت نہ اٹھائی جائے تو صرف شوق بلبلہ بر آب ثابت ہوگا۔
حدیث نبوی صلی اللہ علیہ و آلہٖ وسلم ہے کہ استقامت کرامت سے بھی بڑھ کر ہے۔ ایک شخص محنت شاقہ کا بارگراں اُٹھاتا ہے لیکن اس میں بے قاعدگی کا عنصر موجود ہے، باقاعدگی اور تسلسل کا فقدان ہے تو اس کی محنت رنگ نہیں لائے گی ، اس کے گلشن میں بہارنہیں آئے گی، اس کے کھیت و کھلیان کشتِ زعفران کا نمونہ پیش نہیں کریں گے، اس کے طائران خوش الحان...

How Islam and Democracy are Reconcilable?

The paper discusses in detail different ways how Islamand democracy can be reconciled and highlights the importance of democratic values for Muslim dominated societies, which is the need of modern times. It also discusses how Islam which stands for global peace and security and bound Muslims to be more responsible regarding the implementation of justice, peace and to stand for the fundamental humanitarian values which go in parallel with the concept of democratic principles. The paper also converses, the scenario in which the beautiful religion for entire humanity has been attempted to be hijacked by a radical mindset whichprevailed in every civilization ever existed.

Synthesis and Characteriaztion and Applications of Bimetallic Alloy Nanopariticiles

In this work Ag-Cu, Ag-Au and Au-Cu bimetallic alloy nanoparticles of different compositions were synthesized by different methods i.e., polyol, aqueous polymer solution, co-reduction, reverse micellar, co-precipitation and chemical reduction methods. The synthesized alloy nanoparticles were characterized by UVVisible spectroscopy, fluorescence spectroscopy, XRD, SEM, TEM, HR-TEM and EDS. The XRD pattern showed high crystallinity and phase formation of the nanoparticles. TEM evidenced the formation of Ag-Cu, Ag-Au and Au-Cu nanoparticles with diameters ranging from 10-15, 20-30 and 15-25 nm respectively. Ag-Cu bimetallic alloy nanoparticles were coated over a well-polished glassy carbon electrode and the designed sensor was applied for the detection of a highly carcinogenic carbonyl compound, 2-butanone. Electrochemical studies revealed that polyethylene imine (PEI) used as a capping agent also enhances the sensing of the modified electrode for the recognition of 2-butanone. The sensor developed from AgCu (1:1) alloy nanoparticles showed the best sensing properties for the detection of 2- butanone as evidenced by electrochemical impedance spectroscopy and a 0.1 μM detection limit. Glassy carbon electrode (GCE) was modified with potentiodynamic polymerization of pyrrole into polypyrrole which was over oxidized in order to increase its sensitivity towards polycyclic aromatic hydrocarbons (PAHs). The electrode was further modified with Au-Ag bimetallic alloy nanoparticles. The fabricated GCE was successfully applied to detect an environmental toxin, pyrene. Ag and Au in ratio of 3:1, showed best response for the detection of pyrene with a detection limit of 0.1 µM. Au-Cu (1:3) alloy nanoparticles synthesized by chemical reduction method were intentially engineered with their desired ratio and chemical composition on the surface of clean GCE that was already fabricated with over oxidized poly pyrrole. This composite electrode (PPyox/Au-Cu/GCE) was successfully applied for the detection of environmental toxin anthracene (with lowest concentration, 0.15 μM). The effect of alloy nanoparticles was tested on seed germination frequency, antioxidant activity and biochemical characterization of medicinally important plants, Silybum marianum and Eruca sativa. Chemical composition of alloy nanoparticles, size and shape matters for nanoparticles to exert effect on plants. Phytotoxicity study of nanoparticles showed that bimetallic alloy nanoparticles are more stress inducing factor in plants acting as external factor that disturb the internal mechanisms of plant seeds. In response to the induced stresses, plants release secondary metabolites (protein content, flavonoids and phenolic contents), antioxidants and some important enzymes like super oxide dismutase (SOD) and peroxidase (POD) by their defensive mechanisms. The secondary metabolites produced in response to stress induced by bimetallic nanoparticles were also evaluated and it was found that nanoparticles of small size and high toxicity produce more secondary metabolites. Such secondary metabolites produced in medicinal plants have a great potential in treating the human ailments.
